Technical Field

[0001] This application relates to the field of robotic arm wiring harness fixing devices, and in particular to a robotic arm wiring harness fixing component and a robotic arm. Background Technology

[0002] The primary function of the wire harness fixing structure in a robotic arm is to ensure the safety, order, and stability of wires and cables. The wire harness fixing structure offers numerous benefits, including protecting cables, maintaining a neat layout, reducing vibration impact, facilitating installation and maintenance, ensuring signal transmission quality, and enabling the wire harness to adapt to different application scenarios. Therefore, the design of the wire harness fixing structure is crucial when designing a robotic arm, as it not only affects the arm's reliability and lifespan but also its overall performance.

[0003] There are many existing wire harness fixing structures for robotic arms, varying in size and shape, but each has its own drawbacks. For example, some wire harness fixing structures are complex in overall structure to ensure the connection of multi-axis robotic arms, resulting in high costs; some wire harness fixing structures are of a single size, cannot be adjusted in tightness, and can only be adapted to a single robotic arm, resulting in poor versatility; still other wire harness fixing structures have wire harness through-hole diameters that cannot be adjusted, which restricts the size of the wire harness, making it unable to adapt to different types of robotic arms, and their large size may affect the movement space of the robotic arm.

[0004] Therefore, it is necessary to design a robotic arm harness fixing component to solve the above problems. Utility Model Content

[0005] In view of this, in order to overcome the defects of the prior art, this utility model provides a robotic arm wire harness fixing component and a robotic arm, which effectively solves the problems of complex structure, high cost, single size and inability to adjust tightness of existing robotic arm wire harness fixing structures, as well as the constraint of wire harness size, which affects the movement space of the robotic arm.

[0006] According to a first aspect of the present invention, a robotic arm wire harness fixing component is provided for fixing the wire harness body. The robotic arm wire harness fixing component includes a clamp portion, an abutment fixing portion, and a flexible locking portion. The wire harness body passes through the clamp portion.

[0011] Preferably, there are multiple connecting blocks, which are respectively disposed at both ends of the receiving groove and both ends of the abutment surface; each connecting block has an elongated hole for the flexible locking part to pass through.

[0016] According to this utility model, the robotic arm wire harness fixing component, through the cooperation of the clamp, the abutment fixing part, and the flexible locking part, can fix the wire harness body to the robotic arm body. Because the fixing method uses the elastic flexible locking part, it is applicable to various robotic arm bodies and can be installed at different positions on the robotic arm body, resulting in a wide range of applications and strong versatility.

The overall structure of this robotic arm wire harness fixing component is simple, with few parts, resulting in a small overall size, light weight, low production cost, and easy portability and transportation.

[0030] According to a first aspect of this utility model, a robotic arm wiring harness fixing component is provided, such as... Figures 1 to 5 As shown, the robotic arm wiring harness fixing component is used to fix the wiring harness of the robotic arm. The robotic arm wiring harness fixing component includes a pipe clamp part 1, an abutment fixing part 2, and a flexible locking part 3.

[0031] In the following description, reference will be made to Figures 1 to 5 The detailed structure of the clamp portion 1, the abutment fixing portion 2, and the flexible locking portion 3 of the robotic arm wiring harness fixing component is described in detail. Furthermore, in the description of the embodiment, the robotic arm body 5 refers to the robotic arm, and the wiring harness body 4 refers to the wiring harness.

[0032] like Figures 1 to 5 As shown, in this embodiment, the wire harness body 4 passes through the clamp portion 1, which can be formed into an approximately cylindrical sleeve-like structure for fixing the wire harness body 4. The size of the clamp portion 1 can be changed to accommodate wire harness bodies 4 of different diameters.

[0033] The abutting fixing part 2 has a receiving groove 201 at one end facing the pipe clamp part 1. The pipe clamp part 1 is disposed in the receiving groove 201, and the size of the receiving groove 201 corresponds to the size of the pipe clamp part 1. Since the pipe clamp part 1 is formed into a cylindrical structure and the receiving groove 201 is formed into a semi-circular groove, it can be understood that the diameter of the receiving groove 201 corresponds to the diameter of the pipe clamp part 1 to facilitate docking. The abutting fixing part 2 has an abutting surface 202 at the other end opposite to the receiving groove 201. The abutting surface 202 abuts against the robotic arm body 5, serving to assist in positioning the robotic arm body 5. The abutting fixing part 2 can serve as a connecting element, and can be used to fix the pipe clamp part 1 and the flexible locking part 3. Connecting blocks 204 are provided at both ends of the abutting fixing part 2. The flexible locking part 3 passes through the connecting blocks 204 and surrounds the pipe clamp part 1, the abutting fixing part 2, and the robotic arm body 5. The connecting block 204 can be formed by extending outward from the main body of the abutting and fixing part 2. The flexible locking part 3 can connect the pipe clamp part 1, the abutting and fixing part 2 and the robotic arm body 5 into one unit through the connecting block 204.

[0034] The flexible locking part 3 is connected to the abutting fixing part 2 via the connecting block 204. At the same time, the flexible locking part 3 can also position the robotic arm body 5 and the abutting fixing part 2. Through the flexible locking part 3, the wire harness body 4 can be fixed to the robotic arm body 5.

[0035] This robotic arm wiring harness fastener, through the cooperation of the clamp part 1, the abutment fixing part 2, and the flexible locking part 3, can fix the wiring harness body 4 to the robotic arm body 5. Because the fastening method uses the elastic flexible locking part 3, it is applicable to various robotic arm bodies 5 and can be installed at different positions on the robotic arm body 5, offering wide applicability and strong versatility. Since the wiring harness body 4 is individually inserted into the clamp part 1, different specifications of wiring harness bodies 4 can be matched by changing the size of the clamp part 1, making the assembly of the wiring harness body 4 flexible and further increasing its versatility. The overall structure of this robotic arm wiring harness fastener is simple, with few parts, resulting in a small overall size, light weight, low production cost, and ease of carrying and transportation. Furthermore, since it is connected to the robotic arm body 5 only through the flexible locking part 3, the range of motion of the robotic arm body 5 is not restricted, allowing it to adapt to different specifications of wiring harness bodies 4 and robotic arm bodies 5.

[0036] Preferably, such as Figure 2 and Figure 3 As shown, in this embodiment, the clamp portion 1 may include a first clamp component 101 and a second clamp component 102. Both the first clamp component 101 and the second clamp component 102 have clamp grooves 103. The clamp grooves 103 of the first clamp component 101 and the second clamp component 102 are abutted to form a through hole for the wire harness body 4 to pass through. The clamp portion 1 can be formed by two parts abutting each other, so that by adjusting the distance between these two parts, it can accommodate wire harness bodies 4 of different diameters.

[0037] Preferably, such as Figure 2 and Figure 3 As shown, in this embodiment, the first clamp component 101 and the second clamp component 102 are detachably connected. Both the first clamp component 101 and the second clamp component 102 have corresponding threaded connection holes. The first clamp component 101 and the second clamp component 102 can be detachably connected to each other by using fastening bolts to connect the threads in the threaded connection holes. The distance between the first clamp component 101 and the second clamp component 102 can also be adjusted by adjusting the connection position of the fastening bolts, thereby accommodating wire harness bodies 4 of different diameters.

[0038] Preferably, such as Figure 2As shown in the embodiment, the outer wall of the pipe clamp 1 is provided with a plurality of positioning grooves 104, and the groove wall of the receiving groove 201 is formed with a plurality of positioning protrusions 203. The plurality of positioning grooves 104 and the plurality of positioning protrusions 203 are arranged in a one-to-one correspondence. The positioning grooves 104 can be arc-shaped grooves, and the positioning protrusions 203 can be semi-circular arc-shaped protrusions. The positioning grooves 104 and the positioning protrusions 203 can be connected to each other. Through the connection of the positioning grooves 104 and the positioning protrusions 203, the pipe clamp 1 can be positioned and installed on the abutting fixing part 2, and at the same time, the installation is tight and not easy to fall off.

[0039] Preferably, such as Figure 3 As shown, in this embodiment, the pipe clamp 1 may include a connecting middle section 105 and limiting ends 106. The limiting ends 106 are disposed at both ends of the connecting middle section 105, and the size of the limiting ends 106 is larger than the size of the connecting middle section 105. The size of the abutting fixing part 2 corresponds to the size of the connecting middle section 105. To facilitate the installation of the abutting fixing part 2, the pipe clamp 1 has a connecting middle section 105 in its middle, which can mate with the receiving groove 201. In the axial direction, a limiting end 106 is provided at each end of the connecting middle section 105, and the size of the limiting end 106 is larger than the size of the connecting middle section 105, so that the abutting fixing part 2 connected to the connecting middle section 105 cannot be dislodged in the axial direction.

[0040] Preferably, such as Figure 2 and Figure 4 As shown, in this embodiment, there are multiple connecting blocks 204, which are respectively disposed at both ends of the receiving groove 201 and both ends of the abutment surface 202, i.e., there are four connecting blocks 204. This prevents the flexible locking part 3 from slipping off. Furthermore, each connecting block 204 has an elongated hole 205 for the flexible locking part 3 to pass through.

[0041] Preferably, such as Figure 4 As shown, in this embodiment, the contact surface 202 is provided with a plurality of friction protrusions 206, which can abut against the robotic arm body 5. The plurality of friction protrusions 206 can increase the frictional force when abutting against the robotic arm body 5, and prevent the robotic arm body 5 from slipping off.

[0042] Preferably, such as Figure 5 As shown, in this embodiment, the flexible locking part 3 may include a flexible element 301 and an adjusting element 302, with the flexible element 301 passing through the adjusting element 302. Further, the flexible element 301 is a hook and loop fastener, and the adjusting element 302 is a D-ring. The combination of the hook and loop fastener and the D-ring fastener can be used to fix robotic arm bodies 5 of different sizes. In this embodiment, the hook and loop fastener may include a front side with a rough surface and a back side with a hook surface, and the hook and loop fastener can be adhered to each other through the rough surface and the hook surface. Simultaneously, the hook and loop fastener itself can be an elastic band.

[0043] Preferably, both the clamp part 1 and the abutment fixing part 2 can be injection molded from silicone.

[0044] The assembly method of the robotic arm wiring harness fixing component is as follows: First, with the flexible component 301 facing upwards, wrap it around the robotic arm body 5 and tighten it, while simultaneously inserting the connecting block 204 of the abutment fixing part 2. Place the wiring harness body 4 inside the pipe clamp part 1 and tighten the pipe clamp part 1 with the fastening bolts. Then place the pipe clamp part 1 into the receiving groove 201 of the abutment fixing part 2. At this time, wrap the flexible component 301 around the top of the pipe clamp part 1 and tighten it. Then, pass the hook side of the flexible component 301 through the top of the adjusting part 302 and back through the bottom of the adjusting part 302. After tightening, let the hook side stick to the rough side, and adjust the tightness appropriately according to the size of the robotic arm body 5. The fixing is then complete.

[0045] This robotic arm wiring harness fastener uses a clamp, abutment, and flexible locking mechanism to secure the wiring harness to the robotic arm. The flexible locking mechanism allows for compatibility with various robotic arm bodies and can be installed at different locations, offering wide applicability and versatility. Since the wiring harness is individually inserted into the clamp, different sizes can be accommodated by changing the clamp's dimensions, further enhancing its flexibility and versatility. The fastener's simple structure and few parts result in a small size, light weight, low production cost, and easy portability and transportation. Furthermore, the connection to the robotic arm via the flexible locking mechanism ensures unrestricted movement and allows for compatibility with different wiring harness and robotic arm specifications.

[0046] In addition, such as Figure 6 As shown, a robotic arm is provided according to a second aspect of the present invention, the robotic arm including the robotic arm wiring harness fixing member as described above. During use, the robotic arm uses the robotic arm wiring harness fixing member to fix the wiring harness body 4. Since the wiring harness body 4 is relatively long, multiple robotic arm wiring harness fixing members can be used simultaneously.
